Anybody know the real diff between the black one for PC and the white one for Mac. Specs look the same, would the gestures not be compatible?
I like the black one for my Mac Mini. I'll ask Logitech I guess.

It won't match up as nice with Apple keyboards, but I like the black mouse better. I would love to see Apple dump the white keys on their keyboards now. A keyboard with black keys would look so much nicer with all of their products. Especially with the new Mac Pro, Mac mini and iMac.

Believe me, the logitech KB is better than Apple's. I used Apple's KB for years.
The bt switching instantly from Mac to ipad is nice too. None of that pairing and unpairing nonsense over and over, or battery mess. Loading an unloading batteries in my Magic Mouse wore out the battery door latch. the rechargeble battery in the Logitech kb lasts a long time.

Got the Logitech ultrathin Mouse in black. Amazed at the high quality heavy plastic display case it came in. (save that cost for something more useful, ie. the Apple influence, I guess). Works fine except I can not make it do the zoom gesture. Other stock gestures seem to work fine. It comes with software similar to the Apple mouse one, with videos in the menu to show gestures. Anyone else have one to test? I think it is a software problem. I talked to their support people and filed the info with them.

Not sure if it's a keeper since I use zoom a lot, but also, the super small form factor is giving me some arm pain from my hand having to do a lot of work to hold onto it. Your fingers have to do all the work, you can't use your palm to control or rest cause it's too short, it only fits under your fingers and is so flat. I guess it was not intended for home use. I thought it was their version of the Magic Mouse but I guess it is not. I'll have to see what they have in a fuller size.

I am sofa surfing, it's a little better on a hard surface. Probably best for light use and portability, and no, I have no reason to carry a mouse in my pocket... It's 2/3 the length of the MM and flatter, width is about the same. nice heavy feel tho. Nice materials.
I love the rechargeable battery. Really tired of always loading and charging batteries in my Magic Mouse.

Well the early arm strain it gave me has subsided, but I'm not happy that the zoom gesture does not work. since I'm a 10 footer to the HDTV I use zoom. If it is a software flaw, I hope to see Logitech fix it.

the build quality and materials are first rate and the rechargeability is great. way better than the Magic Mouse in those regards. plus I also use Logitechs backlit BT keyboard, which is excellent also, and recharges.
